Ed is planning daily walking workouts on the same distance of 12 km in the morning and in the evening. usually he is walking at constant rate, however he planned his rate to be 1 km/h more in the morning than in the evening. given he is willing to spend 5 hours and 24 minutes daily on these workouts, what should his morning rate be, in km/h?

Let the rate of walking in the evening be = x km/h

As Ed wants to walk at a rate if 1 km/h more in the morning, then rate in morning becomes = x+1 km/h

So, distance is 12 km, speed is x+1 km/h

Total time is = 5 h 24 m or convert it into hours, it becomes 5.4 hours

Time in morning becomes =

Time in evening becomes =

So equation becomes=

Solving this quadratic equation, we get, x= -5/9 or x=4

As X cannot be negative so neglect -5/9.

Solving by using x=4, we get rate as x= 4+1 =5 km/h

Hence, rate in the morning is 5 km/h.

step-by-step explanation:

because i said it is

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
